Group therapy for substance use disorders: what do we know?

Although group therapy is the most prevalent treatment modality for substance use disorders, an up-to-date review of treatment outcome literature does not exist. A search of the literature yielded 24 treatment outcome studies comparing group therapy to other treatment conditions. These studies fell into one of six research design categories: (1) group therapy versus no group therapy; (2) group therapy versus individual therapy; (3) group therapy plus individual therapy versus group therapy alone; (4) group therapy plus individual therapy versus individual therapy alone; (5) group therapy versus another group therapy with different content or theoretical orientation; and (6) more group therapy versus less group therapy. In general, treatment outcome studies did not demonstrate differences between group and individual modalities, and no single type of group therapy reliably demonstrated greater efficacy than others. Unique methodological and logistical hurdles encountered in research on group therapy for substance use disorders, as well as considerations for future research, are also discussed.

Requiring remission of undue influence of weight and shape on self-evaluation in the definition of recovery for bulimia nervosa.

OBJECTIVE: The current study evaluated the concurrent validity of requiring remission of undue influence of weight and shape on self-evaluation (undue influence) in defining recovery from bulimia nervosa (BN). METHODS: Three groups completed the Beck Depression Inventory, the Mood and Anxiety Symptom Questionnaire, the Body Shape Questionnaire, and the Social Adjustment Scale: 31 women were fully recovered from BN (FR), 28 women had no behavioral symptoms of BN (partially recovered [PR]), and 59 matched non-eating-disordered controls (MC). RESULTS: The PR group had more pathologic scores on depression, anxiety, body dissatisfaction, and social adjustment compared with both the FR and MC groups, which did not differ from each other. DISCUSSION: These findings suggest that including remission of cognitive symptoms in a standardized definition of recovery may prove to be clinically useful in establishing reliable prognostic indicators. Future research should evaluate the role played by cognitive symptoms in triggering relapse.
